OBJECT DESCRIPTION AND IMAGE SESSION

Astronomer John Herschel first observed this galaxy in October 1834. The galaxy is presented in a NW-SE orientation edge on. Its shape is fading out towards the north west. Some pink / reddish region can be distinguish in the image indicating the presence of active star formation regions. A magnitude 13 star is superimposed in the southern east area of NGC 7090 (upper right in the image).

The telescope focal length of 862 mm was far from ideal to image this relative small object, however this wide field of view present the nice wide area.
